ABSTRACT:
A method is disclosed of obtaining from an imagewise exposed photographic element separate records of the imagewise exposure to each of the blue, green and red portions of the spectrum comprising photographically processing an imagewise exposed photographic element comprised of a sequence of superimposed blue, green and red recording silver halide emulsion layer units that produce images of the same hue upon processing (e.g., units lacking a dye-forming coupler). A first interlayer unit overlies the emulsion layer unit nearest the support and is capable of transmitting to it imagewise exposing radiation this emulsion layer unit is intended to record. A second interlayer unit underlies the emulsion layer unit farthest from the support and is capable of transmitting to the emulsion layer units lying nearer the support imagewise exposing radiation these emulsion layer units are intended to record. The imagewise exposed photographic element is photographically processed to produce a silver image in each of the emulsion layer units. After photographic processing one of the interlayer units is capable of absorbing electromagnetic radiation within at least one wavelength region and emitting within a longer wavelength region, and the remaining of the first and second interlayer units is capable of reflecting or absorbing electromagnetic radiation within at least one wavelength region. The photographic element is scanned utilizing emission from one of the interlayer units to provide a first record of the image information in one of the first and last emulsion layer units and is scanned utilizing reflection or absorption of the remaining interlayer unit to provide a second record of the image information in one other of the emulsion layer units. Additionally, the photographic element is scanned through the first and second interlayer units and all of the emulsion layer units to provide a spectrally undifferentiated third record of the combined images in all of the emulsion layer units. The first, second and third records are compared to obtain separate blue, green and red exposure records.
